A field guide for your next dive
Practice deliberately, explore freely.
Choose a course and a focus, or mix its topics. Try a question, sketch your reasoning, then compare the worked steps. Studying a solution does not count as an answered question. The timer is entirely yours to control.
What’s in this ocean?
A first-release collection of representative, parameterized exercises—not a complete syllabus or symbolic algebra system. No general limit engine, convergence test suite, arbitrary-region integration, surface integrals, or Stokes/divergence theorem problems. All choices are exact unless explicitly labeled otherwise. Reloading starts a fresh session.
Privacy, access & notation
No accounts, analytics, external fonts, or third-party scripts. Practice, drawings, and scores stay in this page’s memory. Standard GitHub Pages hosting still receives normal web requests. Formulas use selectable Unicode text, superscripts, explicit bounds, and exp(x) for eˣ. Controls work with keyboard and touch. Light/dark modes follow your device initially; the theme button changes this visit’s appearance.
